Definitions
- the invention relates to an active substance-containing plaster for the controlled release of estradiol or its pharmaceutically acceptable derivatives, alone or in combination with gestagens to human or animal skin, with an active substance-containing reservoir based on pressure sensitive adhesives containing ethyl cellulose and adhesive resins.
- Transdermal therapeutic systems have been known for a long time, in particular also for the transdermal administration of hormones, especially estrogens, optionally in combination with gestagens.
- the active substances are provided in an active substance reservoir on the basis of pressure sensitive adhesives, the stickiness of which must ensure adequate skin contact during application without excessive softening, without skin irritation occurring and the absorption and release of active substances corresponding to the desired continuous systemic supply of active substance via the skin.
- estradiol-containing reservoir layers e.g. DE-OS 32 05 258 and EP 0 275 716.
- DE-OS 39 33 460 describes active ingredient plasters based on homo- and copolymers with at least one derivative of acrylic or methacrylic acid, which are said to additionally contain water-swellable substances.
- DE-PS 40 20 144 an optionally also hormone-containing transdermal system with at least one self-adhesive active substance layer is known which, in addition to polyacrylate and a film former compatible with it, is said to have a wide range of softening active substances and auxiliary substances.
- a recently described transdermal therapeutic system (see DE-OS 195 00 662) comprises an active substance reservoir based on ethyl cellulose containing estradiol and optionally gestagens with a high proportion of esters of optionally hydrogenated rosin as a tackifying resin together with up to 20% by weight. Lauric acid, which is intended to counteract recrystallization of the active ingredient and thus a reduction in its release rate.
- estradiol and in particular norethindrone acetate can be achieved from an active ingredient reservoir based on ethyl cellulose and tackifying resin, which is provided with an exceptionally high proportion of plasticizer.
- the plaster of the type mentioned at the outset is accordingly characterized in that the pressure sensitive adhesive has a high proportion of plasticizer.
- the pressure sensitive adhesive contains at least 15% by weight, preferably at least 20% by weight, of plasticizer.
- the active substance-containing patch can contain emulsifiers, antioxidants and absorption improvers.
- emulsifiers antioxidants and absorption improvers.
- Such a plaster can be used in particular for a high combined release of both estradiol and norethindrone acetate.
- compositions according to the invention have the following composition (in% by weight):
- plasticizers to pressure sensitive adhesive compositions containing active ingredients is known per se, such as also in accordance with the aforementioned DE-OS 40 20 144, however, it is only possible to add a plasticizer to the customary pressure-sensitive adhesives based on polyacrylates, block copolymers and polyisobutylenes to a limited extent, since from a certain concentration the cohesion of the pressure-sensitive adhesives decreases and they therefore become transdermal Application are unsuitable.
- composition of the active ingredient reservoir based on ethyl cellulose / adhesive resin with a high plasticizer content but without lauric acid shows a significantly increased hormone release compared to the compositions according to DE-OS 195 00 662, especially when incorporating a combination of estradiol and norethindrone acetate.
- Tables 1 and 2 show the results of test series on active ingredient exposure.
- plasticizer content according to the invention achieves a significant improvement in the active ingredient release and penetration.
